During the output of docker-puppet.py, the config hashes are updated and the config_volume is printed in the debug lines. The issue is that the config_volume in the logs is not relevant to the action and isn't even apart of the loop so it's printing the same value for all the debug lines. This causes confusion when people are looking into issues as they may see something like:
"2018-02-07 17:12:29,191 DEBUG: 25587 -- Updating config hash for glance_api, config_volume=neutron hash=d56bf79dc985244e36791d68d77c3f15"
Example (config_volume=neutron):
